The central objective of the project is to establish a modeling tool that captures the anisotropy of TRIP/TWIP steels across several length scales under arbitrary thermomechanical loading. The contributions of discrete slip and transformation systems to the overall single crystal properties are taken into account via appropriate homogenization assumptions. The macroscopic material behavior is predicted by means of finite element simulations of multi-crystals as well as RVE calculations for polycrystals. The predictive accuracy of the model is achieved through rigorous calibration and validation on the basis of macro-, meso- and micro-scale experiments conducted within the Collaborative Research Centre (CRC).

该项目的中心目标是建立一个建模工具，捕捉TRIP/TPEST钢在任意热机械载荷下的几个长度尺度的各向异性。通过适当的均匀化假设的离散滑移和转换系统的整体单晶性能的贡献考虑。通过多晶体的有限元模拟和多晶体的RVE计算预测了宏观材料行为。该模型的预测准确性是通过在合作研究中心（CRC）内进行的宏观，中观和微观实验的基础上进行严格的校准和验证来实现的。
